[0002] With the intensification of the global energy crisis and the improvement of environmental awareness, new energy vehicles have become the mainstream trend of future travel with their low-carbon and environmentally friendly characteristics. Governments of various countries are also actively promoting the development of the new energy vehicle industry and have introduced a series of preferential policies and subsidy measures. Against this background, the production and sales of new energy vehicles are growing rapidly, and the demand for battery modules is also increasing.
[0003] In the context of the rapid development of electric vehicle technology, the performance, safety and reliability of power battery modules, as the core components of electric vehicles, have attracted much attention. Power battery modules not only need to have efficient energy storage and output capabilities, but also need to remain stable during vehicle driving to avoid damage caused by vibration or impact. Therefore, the locking mechanism of the power battery module has become a key factor in ensuring the stability and safety of the battery module.

In addition, the bolt tightening method also has the risk of loosening and requires regular inspection and maintenance, which adds additional costs and workload. When the battery module that uses the bolt tightening method needs to be repaired or replaced, the bolts need to be removed one by one, which is a cumbersome and time-consuming process. Especially in emergency situations, such as when the battery module fails and needs to be replaced quickly, the bolt tightening method may delay rescue time and affect the safety and reliability of the vehicle.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0032] Embodiment 1, as Figure 1-Figure 9 As shown, an automobile battery module provided with a locking device of the present invention comprises a mounting groove 1, a battery module 2 is placed in a close fit in the groove of the mounting groove 1, mounting blocks 21 are fixed on both sides of the battery module 2, and a hollow sealing box 11 is provided on one side of the mounting block 21 at the top of the mounting groove 1;
[0033] A clamping assembly 3 is installed on the platforms at both ends of the installation groove 1. The clamping assembly 3 is used to position the assembly block 21. The clamping assembly 3 includes a slide bar B32 fixed on the platforms at both ends of the installation groove 1, and a bidirectional screw rod 31 rotating on the platforms at both ends of the installation groove 1. The two opposite threads at both ends of the bidirectional screw rod 31 are threadedly connected with a clamping block 33. The clamping block 33 slides outside the two slide bars B32, and the clamping block 33 fits the assembly block 21, and an insert block 34 on one side of the clamping block 33 is inserted into the socket of the side wall of the assembly block 21;
[0034] A driving assembly 4 is installed inside the hollow closed box 11. The driving assembly 4 includes a rotating rod 41 rotatably connected to the inside of the hollow closed box 11. The rotating rod 41 drives the clamping assembly 3 to operate to position and release the assembly block 21 by rotating forward and reverse directions. A locking assembly 5 is installed on the rotating rod 41. The driving assembly 4 also includes two bevel teeth 1 42 fixed to the outer wall of the rotating rod 41. The bevel teeth 1 42 are meshed with bevel teeth 2 43, and the bevel teeth 2 43 are connected to the rotating shaft of the bidirectional screw rod 31.
[0035] The locking assembly 5 includes an inner plate 51 fixed on the rotating rod 41, an outer ring 52 is provided on the outside of the inner plate 51, and a stopper 54 is rotatably connected in the recesses on both sides of the inner plate 51. The inner side of the stopper 54 is connected to the inner plate 51 with a spring A55. The inner wall of the outer ring 52 is provided with a circle of limiting bevels 53, and the stopper 54 fits in the limiting bevels 53, and the stopper 54 can only move along the tilting direction of the limiting bevel 53. When the stopper 54 moves along the tilting direction of the limiting bevel 53, the two clamping blocks 33 move sideways to the assembly block 21 and finally fit together.
[0036] As described above, through the design of the locking component 5, when the present invention is working, the battery module 2 is placed in the installation groove 1 to ensure that the groove of the battery module 2 is completely fitted with the installation groove 1. Assembly blocks 21 are fixed on both sides of the battery module 2. In the initial state, the clamping block 33 is in an open state and does not clamp the assembly block 21. When the battery module 2 needs to be clamped, the driving component 4 is started, and two bevel teeth 42 are fixed on the rotating rod 41, and these bevel teeth are engaged with bevel teeth 43. Bevel gear 2 43 is docked with the rotating shaft of the bidirectional screw rod 31, so when the rotating rod 41 rotates, it will drive the bidirectional screw rod 31 to rotate. When the rotating rod 41 rotates clockwise (at this time, the stop block 54 moves along the inclined direction of the limiting bevel 53), bevel gear 1 42 drives bevel gear 2 43 and the bidirectional screw rod 31 to rotate. The rotation of the bidirectional screw rod 31 causes the two clamping blocks 33 to move toward the center on the sliding rod B32 until they are in contact with the assembly block 21. The insert block 34 on one side of the clamping block 33 is inserted into the socket on the side wall of the assembly block 21 to ensure that the battery module 2 is firmly clamped in the mounting groove 1. During the clockwise rotation of the rotating rod 41, the locking assembly 5 also starts to work. The locking assembly 5 includes an inner disk 51, an outer ring 52, a stopper 54 and a spring A55. When the rotating rod 41 rotates, the inner disk 51 rotates accordingly. The inner wall of the outer ring 52 is provided with a circle of limiting bevels 53, and the stopper 54 fits in the limiting bevels 53. When the inner disk 51 rotates clockwise, the stopper 54 moves along the inclined direction of the limiting bevels 53 and is pushed by the spring A55. The inner wall of the outer ring 52 is provided with a circle of limiting bevels 53, and the stopper 54 fits in the limiting bevels 53. When the inner disk 51 rotates clockwise, the stopper 54 moves along the inclined direction of the limiting bevels 53. This movement causes the stopper 54 to push the outer ring 52 outward, thereby producing a locking effect. At the same time, Due to the design of the limiting bevel 53, the stop block 54 can only move along the tilting direction, so the rotating rod 41 is locked in the clockwise direction and cannot rotate in the opposite direction. That is, the structure contains the principle of a ratchet structure, that is, when the rotating rod 41 rotates clockwise, the stop block 54 is pushed to the tilting direction of the limiting bevel 53 like a ratchet pawl, thereby locking the rotating rod 41, allowing the rotating rod 41 to rotate and lock in one direction in the clockwise direction, while preventing it from rotating in the opposite direction, completing the automatic locking, making the battery module 2 very stable and not easy to loosen. It should be noted that when the insert block 34 on one side of the clamping block 33 is inserted into the socket of the side wall of the assembly block 21, the stop block 54 fits in a limiting bevel 53.
[0037] A protrusion 521 is fixed on the top of the outer ring 52, and the protrusion 521 slides outside the three sliding rods A522 fixed inside the hollow closed box 11. A slider 523 is fixed on the top of the protrusion 521, and the slider 523 slides in the internal slide of the hollow closed box 11, and the side of the slider 523 is connected to the internal slide of the hollow closed box 11 with a spring B524.
[0038] In the second embodiment, the design of the protrusion 521, the slide bar A522 and the slider 523 requires the reverse rotation of the rotating rod 41 (assuming it is counterclockwise) when unlocking. Since the protrusion 521 is fixedly connected to the slider 523, the movement of the slider 523 will drive the protrusion 521 to move outward along the slide bar A522, causing the outer ring 52 to be displaced, and then the internal structure of the locking assembly 5 will change, causing the stop block 54 to disengage from the limiting bevel 53. Once the locking of the locking assembly 5 is released, the rotating rod 41 can continue to rotate counterclockwise. This will cause the relative movement of the bevel gear 1 42 and the bevel gear 2 43, and then drive the bidirectional screw 31 to reverse. The reversal of the bidirectional screw 31 will cause the clamping block 33 to move outward on the slide bar B32, loosening the assembly block 21 and the battery module 2, and the spring B524 is easy to reset.
[0039] The slideway where the slider 523 is located is connected to the opening at the top of the hollow closed box 11, and a closing plate 14 is rotatably connected to one side of the opening. The opening is used to move the slider 523. A cylinder 44 is fixed to one side of the hollow closed box 11 and a cylindrical block 45 is rotatably installed. The cylindrical block 45 is inside and close to the cylinder 44, and the cylindrical block 45 is docked with the rotating shaft of the rotating rod 41, and the side of the cylindrical block 45 is aligned with the cylinder 44, and a horizontal bar-style groove is provided on the side of the cylindrical block 45, and a horizontal bar-style groove is also provided on the top of the slider 523.
[0040] Embodiment three, when unlocking, it is also necessary to open the closing plate 14 so as to directly access the slide opening where the slider 523 is located. Once the closing plate 14 is opened, the operator can use a corresponding tool (such as a slender rod-shaped or bar-shaped object, the end of which may have a horizontal bar style structure that matches the top groove of the slider 523) to move the slider 523. This tool is inserted into the slide opening and moved along the slide to a position opposite to the top groove of the slider 523. Then, the operator can gently move the tool so that the end of the tool contacts the groove of the slider 523 and generates sufficient force to overcome the thrust of the spring B524. While this force is continuously applied, the slider 523 will start to move along the slide, and the cylindrical block 45 will rotate in the same way. After completing the disassembly, the operator can close the closing plate 14 to close the slide opening, thereby preventing dust or other debris from entering the hollow closing box 11. This can prevent theft and make the operation more rigorous. Only designated manufacturers need designated tools, or the tools can be prepared in the vehicle for easy maintenance and disassembly outside to avoid misoperation.
[0041] Circular tubes 12 are provided on both sides of the hollow closed box 11. The outlet of the circular tube 12 at the inner end of the hollow closed box 11 is located at the meshing position of the bevel gear 1 42 and the bevel gear 2 43 for adding lubricating oil, so that the adding pipe can pass through the circular tube 12 for operation.
[0042] Two convex strips 13 are fixed on both sides of the mounting groove 1, and corresponding grooves are provided on both sides of the battery module 2. When the battery module 2 is placed from top to bottom, the convex strips 13 are inserted from the bottom of the groove to form a sliding connection, which plays a limiting role during placement and enhances the firmness of the connection.
[0043] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
